Add remote dimming functionality to your in-wall light switch with the Shelly Dimmer2 Smart Wi-Fi Module, No Neutral. This Wi-Fi connected dimmer module fits behind your light switch to issue On/Off/Dim/Brighten commands over a connected light through the switch, or remotely via your smartphone, tablet, PC, or home automation system. This device does not require a smart hub to operate, which provides you faster installation time and versatile control as either a stand-alone device or added later into a smart home system. This Wi-Fi dimmer module features 0-10V outputs for various applications as well as 2 switch/button inputs (SW1 and SW2) for light control and 2 power supply inputs (1N and 1L) for Live terminals. It supports remote commands for multiple types of drivers including lights, motors, valves, fan speed, and can even be integrated into home automation scenes such as turning on or dimming a connected light when motion is detected (motion sensor required, sold separately).
